It seems that you are right and something is wrong with module.
What about other inputs? If other inputs are fine than this one input is damaged, if other inputs are the same that it seems that analog amplifier is damaged. Have you tried to connect more than 5,5volt signals to 0-5V inputs? Please send us unit (module only) for tests (and service), I'm sending you details on PM.
